将Spring Boot从1.5.12迁移到1.5.13后，ehcache提供错误

Question

我已经配置了Spring Boot 1.5.12 + ehcache，一切正常，直到我将Spring Boot升级到1.5.13

application.yml 具有以下条目

spring:
  cache:
    jcache:
      provider: org.ehcache.jsr107.EhcacheCachingProvider
      config: ehcache.xml

我ehcache.xml位于resources目录下

我收到的错误是：

    ... 47 common frames omitted

看来Spring Boot已开始搜索ehcache.xml使用ServletContext解析器。

ps：除了将Spring Boot升级到1.5.13之外，我没有任何源代码更改

我在这里缺少一些必需的配置吗？

我已经找到解决此问题的方法。我们需要classpath:使用文件名指定前缀以使其起作用。

我application.yml现在看起来像这样

spring:
   cache:
     jcache:
        provider: org.ehcache.jsr107.EhcacheCachingProvider
        config: classpath:ehcache.xml

希望能有所帮助。
